Description
図2は、空調装置10の暖房モードについて説明する図である。暖房モードは、車室内を暖房する場面で稼働するモードである。
図3は、空調装置10の冷房モードについて説明する図である。冷房モードは、車室内を冷房する場面で稼働するモードである。
切替弁86は、冷却水流路81から流入する冷却水を冷却水流路82に流通させるかバイパス流路85に流通させるかを切り替える。
図4は、温度調整システム1の第一冷却モードについて説明する図である。第一冷却モードは、バッテリ84の発熱などによってバッテリ84を冷却する必要がある場面で稼働するモードである。
図5は、温度調整システム1の加熱モードについて説明する図である。加熱モードは、バッテリ84の温度を上昇、維持、または温度下降を鈍化させる必要がある場面で稼働するモードである。
図6は、温度調整システム1の第二冷却モードについて説明する図である。第二冷却モードは、第一冷却モードよりもさらにバッテリ84を冷却する必要がある場面(例えば、バッテリ84を急速充電したい場面)で稼働するモードである。すなわち、第二冷却モードは、バッテリ84の最大冷却モードである。
図7は、温度調整システム1の補助暖房モードについて説明する図である。補助暖房モードは、暖房モードでは車室内の暖房を充分に行うことができない場面(例えば外気が極低温(例えば−20℃以下)であるために室外熱交換器44にて外気から熱を充分に取り込むことができない場面)で稼働するモードである。
